Tracing.Client

Shared distributed tracing configuration with OpenTelemetry for all SaaS services.

Features

Auto-instruments ASP.NET Core (inbound HTTP requests)
Auto-instruments HttpClient (outbound HTTP calls)
Auto-instruments Entity Framework Core (database queries)
Auto-instruments MassTransit (RabbitMQ message consumers/publishers)
Exports traces via OTLP to Jaeger or any OTLP-compatible backend
Configurable sampling rate (100% in dev, 10% in production)
W3C TraceContext propagation out of the box
Graceful no-op when Jaeger is not running

Quick Start

// In Program.cs (builder phase)
builder.AddTracingDefaults(opts => opts.ServiceName = "IdentityService");

Configuration

Via appsettings.json

{
  "Tracing": {
    "ServiceName": "IdentityService",
    "SamplingRatio": 0.1,
    "OtlpEndpoint": "http://jaeger:4317",
    "InstrumentEfCore": true,
    "InstrumentMassTransit": true,
    "IncludeDbStatements": false
  }
}

Via Environment Variables

Variable	Description
`Tracing__OtlpEndpoint`	OTLP endpoint (maps to `Tracing:OtlpEndpoint` config key)
`Tracing__SamplingRatio`	Sampling ratio (0.0 to 1.0)
`Tracing__Enabled`	Enable/disable tracing entirely

Note: The standard OTEL_EXPORTER_OTLP_ENDPOINT env var is intentionally NOT read by this package to avoid conflicts with .NET Aspire's UseOtlpExporter(). Use Tracing__OtlpEndpoint.

Via Docker Compose

environment:
  - Tracing__OtlpEndpoint=http://jaeger:4317
  - Tracing__SamplingRatio=0.1

Design Decisions

No-op when no endpoint: If Tracing:OtlpEndpoint is empty (or the Tracing__OtlpEndpoint env var is unset), traces are collected but not exported. Services start without errors even if Jaeger is down.
MassTransit: MassTransit 8.x has built-in OpenTelemetry via System.Diagnostics.Activity. We add its ActivitySource name so the OpenTelemetry SDK captures those spans automatically.
Sampling: Defaults to 100% in development. Set to 10% in production via config or env var.
